Event-free survival (EFS) in MATTERHORN: A randomized, phase 3 study of durvalumab plus 5-fluorouracil, leucovorin, oxaliplatin and docetaxel chemotherapy (FLOT) in resectable gastric/gastroesophageal junction cancer (GC/GEJC)

Rapid Readouts

Rapid Readouts is a video program featuring leading experts who provide in-depth reviews of the most pivotal and practice-changing data that have been unveiled at recent medical oncology conferences. In each video, top oncologists in their specialty present slides and posters from these annual symposiums and meetings, while highlighting the ever-changing landscape of treatment choices for patient management.

Presented by Yelena Y. Janjigian at ASCO 2025, the Phase 3 MATTERHORN study demonstrated that adding durvalumab to FLOT significantly improved event-free survival compared with FLOT alone in patients with resectable gastric and gastroesophageal junction adenocarcinoma, with consistent benefit across subgroups and no new safety concerns.
